This post includes a PowerShell Get-ChromeExtension script to list installed extensions on the local or remote computer.
Browser extensions are supposed to be curated and vetted, but there have been many examples of malware. If you don’t already have control of extensions through an allow or blocklist, the first step is to find out what is in-use.
The code below is a PowerShell function to get the installed Google Chrome browser extensions from a local or remote Windows computer.
Chrome Browser Extensions install into the user profile and do not appear in the Add/Remove Programs list.
Chrome Extensions are a challenge to audit due to the way they install and lack of enumeration options. The PowerShell script below gets the installed extensions using the following method:
- Get the extension IDs from the folders names under
%userprofile%\AppData\Local\Google\Chrome\User Data\Default\Extensions - Lookup the extension name on the Chrome Web Store using the extension ID
- Get the extension version from the
manifest.jsonfile in the extension folder
Example script output
C:\> Get-ChromeExtension | Select Name,Version,Description | ft -AutoSize
